Relax the object locking in vm_pageout_map_deactivate_pages() and

Add the combined (mixed) diversity support capability bit for the

Similar to r251236, r251242, and r251244. Introduce new function-pair to
dialog(1) API in dialog.subr responsible for retrieving menu-choice data
(for the --menu widget).

Add f_dialog_menuitem_store()/f_dialog_menuitem_fetch() for storing and
retrieving the menuitem (not the tag) from a --menu widget result.

The dialog --menu widget returns the `tag' from the tag/item pair of choices
for a menu list. Because the menu list is often local to the function that
is displaying it, the ability to dereference this into the item is not
possible unless you use a global. This changes things so the function (upon
successful return of dialog) dereferences the tag into the item and stores
it for later retrieval using these functions.

NOTE: Tags are dereferenced into items using f_dialog_menutag2item().
Comments.
Use a case-statement instead of multiple (separate even) if-statements.
Use f_shell_escape() instead of forking to awk. In this case, the
replacement comes with a great performance increase (as f_shell_escape()
uses the built-in based f_replaceall() which out-performs forking to
awk(1)). This should also improve readability slightly.
Add man links for expl(3) and expm1l(3).
Update a comment.
Match the options of the kernel.
mdoc: convert .Fd to .In, which is much nicer.
Implement pmap_copy() for ARMv6/v7.

Copy the given range of mappings from the source map to the
destination map, thereby reducing the number of VM faults on fork.

Lessen verbosity of "Exit" menutag items to appear more consistent across
menus from one module to the next.

Replacing "Exit this menu (returning to previous)" with "Exit this menu".

Shift Console->Saver menu items to place the default item at the top, making
this menu consistent with Console->Repeat, Console->Font, Console->Screenmap
and many others which place the default choice at the top.

NOTE: SVN r249751 changed things so that these menus highlight the active
selection, so the idea that the default choice (now at top) "can be selected
immediately by hitting ENTER" is not possible unless the default choice is
the currently active setting (e.g., on first visit to the menu). However, it
is still warranted to have the default choice at the top of the menu.
